Abstract

The physicochemical properties of synthesized TiO2 nanoparticles from integrating sol-gel with flame-based techniques were studied. The synthesized nanoparticles properties were compared after using methanol, ethanol, and propanol fuel sources. The synthesized TiO2 were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), thermal analysis (thermogravimetric analysis, TGA, and differential scanning calorimetry, DSC), and surface area Brunauer–Emmett–Teller (BET) method. The photocatalytic activity of TiO2 nanoparticles was investigated by measuring the degradation of methylene blue. It was found that methanol and ethanol burners can be used as an alternative furnace that can yield TiO2 nanoparticles with physicochemical properties comparable to that of commercial TiO2 nanoparticles, while a propanol burner cannot be used as an alternative fuel.
